Re: Overclocking Intel Core 2 Duo E6600 2.4GHz/1066
Teh Capt's right SLippe, more vCore needed. My old Striker seemed to need alot of volts, I had it at 1.5v @ 3.36Ghz.
400Mhz FSB is a good OC cos like you said, you can run your memory at a 1:1 ratio. I would try again with higher vCore, 1.45v ish, if it's stable at that clock, drop the vCore to find the minimum vCore for that speed.
Have you disabled the 'spread spectrum' options, that usually helps. The P35 chipset can generally get well over 450Mhz.
